Publication number: 20100316328Abstract: Fiber optic position transducer that includes a magnetic or electromagnetic element, one or more segments of magnetostrictive material, Fiber Bragg Grating Sensors, a rod of material that is impenetrable to magnetic fields, optical fiber. One or more of the sensors is fixed upon a segment of magnetostrictive material, which is fixed to a rod, and may only be displaced longitudinally. The Fiber Bragg Grating Sensors have different wave lengths and are made of the same optical fiber. The magnetic or electromagnetic element included may be made of NdFeB (Neodymium Iron Boron) or metal alloys of TbDyFe (Terbium, Dysprosium and Iron), such as TX, Terphenol-D and others. It is applied to a control flow valve in an oil well, and it also refers to the calibration process of the position of the transducer.Type: ApplicationFiled: December 28, 2009Publication date: December 16, 2010Applicants: PETROLEO BRASILEIRO S.A. - PETROBRAS, PONTIFICIA UNIVERSIDADE CATOLICA DO RIO DE JANEIROInventors: José Luiz Arias Vidal, Ricardo Munoz Freitas, Arthur Martins Barbosa Braga, Luiz Carlos Guedes Valente, Antônio Carlos Oliveira Bruno, Hélio Ricardo Carvalho

Patent number: 7266261Abstract: A fiber optics differential pressure transducer (100, 200, 300, 400) containing Bragg networks (118), said transducer being used to measure the differential pressure in a Venturi installed inside a pipe (1), through which a fluid like oil is displaced. The transducer comprises a body (110, 230, 360, 410) of different geometries and a diaphragm (2), at least one Bragg network (118) being attached on each of the surfaces of the same. The diaphragm (2) is placed parallel or transversal to the transducer's body (100, 200, 300, 400). The transducer (200) is isolated from the process fluid by flexible mechanical seals (201) which transmit the pressure up to surfaces of the diaphragm (2). The transducer (300, 400) is provided with two relief microvalves for the purpose of protecting the sensor [diaphragms (2)] in overpressure events.Type: GrantFiled: September 9, 2005Date of Patent: September 4, 2007Assignee: Petroleo Brasileiro S.A.-PetrobrasInventors: Jose Luiz Arias Vidal, Manoel Feliciano da Silva, Jr., Ricardo Munoz Freitas, Arthur Martins Barbosa Braga, Luiz Carlos Guedes Valente, Roberth Waldo Angulo Llerna

Patent number: 7251384Abstract: An optical fiber pH sensor 100, 200, 300 is described, where a transducer mechanically couples a Bragg grating to a pH-sensitive hydrogel, said sensor comprising a central part 110, 210, 301 where are placed the optical fiber 121 containing a Bragg grating 122, the pH-sensitive hydrogel set of discs 130, and the mechanical transducer which is a spring 123 a beam 215 or still the optical fiber itself 121, the mechanical transducer assuring the strain on the Bragg grating 122. The change in hydrogel hydrodynamic volume resulting from a change of the pH of the medium introduces a force that is sufficient to cause a strain in the Bragg grating. The measure of the pH change is retrieved using the usual techniques for wavelength measurement. The pH sensor 100, 200, 300 of the invention is useful for the indirect evaluation and control of corrosion in petroleum wells and is suitable for multiplexing with other optical fiber sensors measuring the same or different parameters.Type: GrantFiled: May 26, 2005Date of Patent: July 31, 2007Assignee: Petroleo Brasileiro S.A. - PetrobrasInventors: Manoel Feliciano da Silva Junior, Arnaldo Rodrigues D'Almeida, Fabio Pereira Ribeiro, Luiz Carlos Guedes Valente, Arthur Martins Barbosa Braga, Adriana Lucia Cerri Triques

Patent number: 6658171Abstract: Method and apparatus for polarizing light propagating in an optical fiber. The apparatus has an optical fiber having a Fiber Bragg Grating (FBG) section of predetermined length therein, and a force applying device for applying a lateral force to a predetermined portion of the FBG section. The predetermined portion comprises a predetermined percentage of the predetermined length. When the predetermined percentage is equal to or greater than about 10 percent, two polarization states for the light passing through the optical fiber are obtained. When the predetermined percentage is a small portion of the grating length, for example, about 1 percent of the length of a chirped grating, a finely tunable optical fiber polarizer is provided. The apparatus can use standard optical fiber such as telecomm fiber and provides various advantages including the capability of being switched on and off by simply applying and withdrawing the lateral force.Type: GrantFiled: January 21, 2002Date of Patent: December 2, 2003Assignee: Ericsson Telecomunicacoes S.A.Inventors: Luiz Carlos Guedes Valente, Pedro Ignacio Torres Trujillos
